Answer:
Kc = 6x10⁻⁶
Explanation:
For the reaction:
4NH₃(g) + 3O₂(g) ⇄ 2N₂(g) + 6H₂O(g)
Kc is defined as:
Kc =[N₂]² [H₂O]⁶ / [NH₃]⁴ [O₂]³
The equilibrium concentrations of the gases is -Because volume of the container is 1.00L-:
[N₂] = 2X = 1.96x10⁻³; <em>X = 9.8x10⁻⁴</em>
[H₂O] = 6X; 6ₓ9.8x10⁻⁴ = 5.88x10⁻³
[NH₃] = 0.0150M - 4X = 0.01108M
[O₂] = 0.0150M - 3X = 0.01206M
Replacing in Kc expression:
Kc =[1.96x10⁻³]² [5.88x10⁻³]⁶ / [0.01108M]⁴ [0.01206M]³
<h3>Kc = 6x10⁻⁶</h3>
Explanation:
to remind people that atoms were
Answer:
34.9 mL
Explanation:
First we <u>convert 23.6 g of LiBr into moles</u>, using its <em>molar mass </em>(86.845 g/mol):
- 23.6 g ÷ 86.845 g/mol = 0.272 mol LiBr
Now we can <u>calculate the required volume</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- liters = moles / Molarity
- 0.272 mol / 7.8 M = 0.0349 L
We can <u>convert L into mL</u>:
- 0.0348 L * 1000 = 34.9 mL
